AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 389,500, datedSeptember 11, 1888.

Application filed April 11, 1888. Serial No. 270,248.

To all whom it may concern.-

Be it known that I, SAMUEL HARNEY C01- TRELL, a citizen of the UnitedStates, residing at Ramsey, in the county of Sumter and State ofAlabama, have invented certain new and useful Improvements inAxle-Lubricators; and

I do declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which :0 it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon,which form a part of thisspecification.

My invention has relation to axle-lubricators; and it consists in thenovel construction and arrangement of its parts.

Inthe accompanying drawings, Figure 1 is a perspective view of myinvention. Fig. 2 is a longitudinal sectional view of Fig. 1 cut throughon the line mm. Fig. 3 is a top. plan view of the oil-box. Fig. 4: is aface view of the spindle-nut.

My invention is described as follows: The

2 5 axle-tree A has its upper face perfectly straight and flat. SpindleB has a groove, 12, running along its top its entire length. The woodencasing (J has its lower face perfectly straight and flat, so as to makea perfect joint between 0 itself and the axle A.

D is the oil-tank, which is set in the wooden casing O. This tank has oneach end extending from its upper edge perforated lips (I, by means ofwhich it is secured in said casing C 3 5 by screws (1. From the bottomand front end of said tank a tube, E, extends downward until it reachesthe upper face of the axle A, then turns sharply to the right, runsalong the axle until its end reaches and is embedded 0 in the groove b.In the bottom of said oiltank is an opening, e, for the purpose ofallowing the lubricating material to pass out into the tube E, thenceinto the groove 1), from which sufficient escapes to lubricate the spin-4 5 dle. The said openinge is closed bya threaded thumb-screw, e, whichis so constructed that I may regulate the flow of the lubricating nia-(No model.)

terial or entirely out off the supply. The said oil-tank is providedwith astove-top lid, F, which is made to fit perfectly, and its upperface is flush with the upper edge of said tank. This lid F is held inplace by means ofaspringcover, G, which is pivoted to the upper face ofthe wooden casing 0.

Around the spindle B at its shoulder is a washer, H, which serves thedouble purpose of protecting the end of the tube E and of keeping mudfrom getting into the groove 1).

The spindlenut I has besides its threaded opening i asmall opening, *5.The threads on the said nut are so cut with respect to the threads onthe end of the spindle that when the nut is screwed home the saidopening i will not be opposite the groove 1), but it is so cut that byturning the said nut back a little it may be brought on a line with saidgroove 1), when a small rod may be run through said opening and alongsaid groove to clean it out in case it becomes stopped up.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The combination of the axle A, having the grooved spindle B, woodencasing O, fitting on the upper face of said axle, oil-tank D, providedwith the perforated lips d and countersunk in said casing, and havingthe tube E, extending from the opening 6 in its bottom and terminatingin the groove b,thumbscrew 6, adapted to close partly or entirely saidopening a, and spring-cover G, adapted to close said oil-tank,substantially as shown and described.

2. The combination of the axle A, provided with the groove-spindle B,washer H, and spindle-nut I, having the threaded opening i and smoothopening i, casing O, fitting on the upper face of said axle, oil-tank D,secured in said casing and having the tube E, adapted to conduct the oilinto the groove 1), thumbscrew 0, adapted to regulate the flow of theoil, stove-lid F, fitting in the top of said tank, and spring-cover G,adapted to hold said lid in place, substantially as shown and described.

3. In combination with an axletree having In testimony whereof Iailix mysignature in a groove-spindle, the oil-tank D, provided presence of twowitnesses. with the perforated lips d, stove-lid F, opening 0, tube E,running from said opening 6 SAMUEL HARNEY COTTRELL. 5 and terminating ina groove of the spindle,
